| Abstract: | A thermal lens spectrophotometry having a differential response is describes. The reference and unknow samples are located on opposite sides of the waist of a single gaussian laser beam. The measurble concentrations of cobalt by the single-cell and dual-cell forms are 5ng/ml and 2ng/ml respectively. The sensitivity is increased 10 times compared with normal spectrophotometry by using 2mW available power of a He-Ne laser. |
